For housing affordability and CO2 reduction reasons, giant underground parking parking lots need to be less prevalent kinda soon. They require huge amounts of concrete, which has significant CO2 emissions, and they're so expensive to build they inflate the price of housing (one of these spots costs tens of thousands). Not to say that we need to go back to surface parking. No we just need to change our cities and transportation networks so that people don't need the parking to begin with.
